简要总结
This randomized phase II trial studies how well temsirolimus with or without megestrol acetate and tamoxifen citrate works in treating patients with endometrial cancer that has spread to other places in the body and usually cannot be cured or controlled with treatment, has returned after a period of improvement, or is persistent. Temsirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Estrogen can cause the growth of endometrial cancer cells. Hormone therapy using megestrol acetate and tamoxifen citrate may fight endometrial cancer by blocking the use of estrogen by the tumor cells. It is not yet known whether temsirolimus is more effective when given alone or together with megestrol acetate and tamoxifen citrate in treating endometrial cancer.
详细描述
PRIMARY OBJECTIVES:
I. To determine the response rate of patients with advanced, persistent, or recurrent endometrial cancer when treated with each of the arms of the trial; the proposed arms are: Arm #1 temsirolimus intravenously (IV) weekly, Arm #2 megestrol (megestrol acetate)/tamoxifen (tamoxifen citrate) plus temsirolimus IV weekly.
II. Time to progression and number of patients remaining on study therapy at 24 weeks.
SECONDARY OBJECTIVE:
I. To describe the toxicities of each of the arms of the trial when used for patients with advanced/metastatic endometrial cancer.

入选标准
- •Patients must have histologically confirmed advanced (International Federation of Gynecologists and Obstetricians [FIGO] stage III or IV), persistent, or recurrent endometrial carcinoma, which is not likely to be curable by surgery or radiotherapy; histologic documentation of the recurrence is not required
- •All patients must have measurable disease; measurable disease is defined as at least one lesion that can be accurately measured in at least one dimension (longest dimension to be recorded); each lesion must be >= 20 mm when measured by conventional techniques, including palpation, plain x-ray, computed tomography (CT), and magnetic resonance imaging (MRI), or >= 10 mm when measured by spiral CT
- •Patients must have at least one "target lesion" to be used to assess response, as defined by Response Evaluation Criteria In Solid Tumors (RECIST); tumors within a previously irradiated field will be designated as "non-target" lesions unless progression is documented
- •Prior chemoradiotherapy for a pelvic recurrence is permitted; prior chemotherapy in the adjuvant setting for stage I, II, or III disease is permitted
- •Note: no prior chemotherapy in the setting of stage IV disease is permitted unless the patient was without evidence of disease at the completion of chemotherapy and had at least six months of progression-free survival since the completion of chemotherapy
- •Regardless of circumstances, no more than one prior chemotherapy regimen (including chemoradiotherapy) is permitted
- •Patient must be able to take p.o. medications
- •Performance status must be 0-2
- •Absolute neutrophil count >= 1,500/mcL
- •Platelets >= 100,000/mcL
- •Total bilirubin within normal institutional limits
- •Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT]) =< 2.5 times institutional upper limit of normal v 3.0 (=< 5 times upper limit of normal [ULN] for subjects with liver metastases)
- •Alkaline phosphatase =< 2.5 times institutional upper limit of normal v 3.0 (=< 5 times ULN for subjects with liver metastases)
- •Creatinine =< 1.5 times normal institutional upper limit of normal
- •Cholesterol =< 350 mg/dL (fasting)
- •Triglycerides =< 400 mg/dL (fasting)
- •Albumin >= 3.0 mg/dL
- •At least 4 weeks must have elapsed since the patient underwent any major surgery (e.g., major: hysterectomy, resection of a lung nodule-minor: a Port-A-Cath placement)
- •Patients who have met the pre-entry requirements
- •Patients must have signed an approved informed consent including Health Insurance Portability and Accountability Act (HIPAA) authorization
排除标准
- •Patients with Gynecologic Oncology Group (GOG) performance status of 3 or 4
- •Patients cannot be receiving enzyme-inducing antiepileptic drugs (EIAEDs; e.g., phenytoin, carbamazepine, phenobarbital) nor any other cytochrome P450, family 3, subfamily A, polypeptide 4 (CYP3A4) inducer such as rifampin or St. John's wort, as these may decrease temsirolimus levels; use of agents that potently inhibit CYP3A (and hence may raise temsirolimus levels), such as ketoconazole, is discouraged, but not specifically prohibited; the appropriateness of use of such agents is left to physician discretion
- •All concomitant medications must be recorded at baseline
- •Patients on maintenance corticosteroids are ineligible with the exception of short term use (fewer than 5 days)
- •Patients known to have congestive heart failure; patients with baseline requirement for oxygen; patients with serious concomitant illness that, in the opinion of the treating physician, will place patient at unreasonable risk from therapy on this protocol
- •Patients with a history of unprovoked deep vein thrombosis (DVT) or pulmonary embolism (PE), unless patient is maintained on anticoagulation for the duration of the trial; while the exact definition of "provoked" is left to the treating physician, a DVT in the setting of pelvic surgery or trauma would be considered "provoked"
- •Women of child-bearing potential must have a negative pregnancy test prior to treatment on study; breastfeeding should be discontinued if the mother is treated with temsirolimus
- •Women of child-bearing potential and men must agree to use adequate contraception (barrier method of birth control or abstinence; oral contraceptives [also known as "the pill"] are not acceptable) prior to study entry and for the duration of study participation; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
- •Patients with a concomitant invasive malignancy or a history of other invasive malignancies, with the exception of non-melanoma skin cancer, are excluded if there is any evidence of other malignancy being present within the past five years; patients are also excluded if their previous cancer treatment contraindicates this protocol therapy
- •Patients who have received hormonal therapy or biologic therapy as treatment for endometrial carcinoma
- •Patients who have received chemotherapy directed at metastatic or recurrent endometrial carcinoma

结局指标
主要结局
Percentage of Participants With a Confirmed Objective Tumor Response Using RECIST Version 1.0
时间窗: Radiologic tumor evaluations at baseline and every 6 weeks for the first 24 weeks; then repeated every 12 weeks until disease progression. Repeat after treatment discontinuation if patient was taken off study for reasons other than progression.
RECIST 1.0 defines complete response as the disappearance of all target lesions and non-target lesions and no evidence of new lesions documented by two disease assessments at least 4 weeks apart. Partial response is defined as at least a 30% decrease in the sum of longest dimensions (LD) of all target measurable lesions taking as reference the baseline sum of LD. There can be no unequivocal progression of non-target lesions and no new lesions. Documentation by two disease assessments at least 4 weeks apart is required. In the case where the ONLY target lesion is a solitary pelvic mass measured by physical exam, which is not radiographically measurable, a 50% decrease in the LD is required. These patients will have their response classified according to the definitions stated above. Complete and partial responses are included in the objective tumor response rate.
